The highly aggressive adult sarcomas are characterized by high levels of matrix metalloproteinase (MMP)-2 and -9, which play crucial roles in tumor invasion and metastasis by degradation of the extracellular membrane leading to cancer cell spread to distal organs. We examined the effect of cytokines, mitogens, inducers and inhibitors on MMP-2 and MMP-9 secretion in chondrosarcoma (SW-1353), fib...

Zonampanel monohydrate (YM872) has a potent and selective antagonistic effect on the glutamate receptor subtype, alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor. Metabolic fingerprinting in rat urine after a single intravenous administration of (14)C-labeled YM872 ((14)C-YM872) revealed the presence of two metabolites, R1 and R2. The two metabolites were semi-purified b...

Cholesteryl ester transfer protein (CETP) is a key protein involved in the reverse cholesterol transport pathway. The regulation of CETP by dietary fats is not clearly understood. Transgenic mice expressing human CETP under the control of its natural flanking region were fed low- or high-fat diets enriched in monounsaturated fatty acids (MUFAs) or saturated fatty acids in the presence or absenc...

seed weight (sw) in oilseed rape (brassica napus l.) is determined during the seed filling period (sfp). a great proportion of variation in sw is associated with environmental conditions in this period. to quantify factors determining sw in open pollinated (op) and hybrid cultivars of oilseed rape, 12 field experiments were conducted at agricultural research station of gonbad, iran, during 2000...

Two Gram-negative, non-motile, non-spore-forming, rod-shaped strains, SW-2T and SW-26, were isolated from sea water of the East Sea in Korea. These organisms grew optimally at 37 degrees C and in the presence of 2-3 % (w/v) NaCl. They did not grow without NaCl or in the presence of >9 % (w/v) NaCl. Strains SW-2T and SW-26 were characterized chemotaxonomically as having MK-7 as the predominant i...

Description and meristic analysis of eleven species of Microcyclops recorded in America were performed based on the examination of type specimens and fresh material. Microscopic analysis of oral appendages, such as the shape and armature of the distal coxal endite of the maxilla, the ornamentation on the caudal surface of the antenna, and the intercoxal sclerites and armament of the inner basis...

Polymorphonuclear neutrophils (PMNs) are potent effectors of inflammation and their attempts to respond to cancer are suggested by their systemic, regional and intratumoral activation. We previously reported on the recruitment of CD11b+ leukocytes due to tumor site-specific enrichment of TNF activity after intravenous administration of a dimeric TNF immunokine with specificity for fibroblast ac...

Cardiac output (CO) and regional blood flow to various tissue were measured by means of gamma-labeled plastic microspheres (15 +/- 3 micrometers) injected into the left ventricle during 30-min infusion of l-norepinephrine (NE:4 micrograms(kg.min)) or the same amount of saline (11 microliters/min per animal) in rats physically trained by 2-hr swimming in water of 32 (SW-32), 36 (SW-36), and 38 d...

Some freshwater (FW) teleosts are capable of acclimating to seawater (SW) when challenged; however, the related energetic and physiological consequences are still unclear. This study was conducted to examine the changes in expression of gill Na(+)-K(+)-ATPase and creatine kinase (CK) in tilapia (Oreochromis mossambicus) as the acute responses to transfer from FW to SW. After 24 h in 25 ppt SW, ...
